Ecology part 2
Across
- 2. type of plant that lacks vascular tissues, moves substance slowly from cell to cell by osmosis and diffusion, and grows only in a damp environment
- 4. a fern's thick underground stem that functions as a food-storage organ
- 6. adaptive reproductive structure of some vascular plants that contains an embryo, nutrients for the embryo, and is covered by a protective coat
- 9. seed structure that stores food or helps absorb food for the sporophyte of vascular seed plants
- 11. liverwort with a fleshy, lobed body shape
- 12. openings in the other cell layer of leaf surfaces and some stems that allow the exchange of water, carbon dioxide, oxygen, and other gases between a plant and its environment
Down
- 1. specialized tissue that transports water, food, and other substances in vascular plants and can also provide structure and support
- 3. a feature that contains male or female reproductive structures of cycads and other gymnosperms
- 5. a plant that lives anchored to an object or to another plant
- 6. a compact cluster of spore-bearing structures in some seedless vascular plant sporophytes
- 7. type of plant with vascular tissues adapted to land environments
- 8. a fern structure formed by clusters of sporangia, usually on the underside of a food
- 10. sac or case in which fungal spores are produced
